This study aims to investigate the correlation between build orientation characteristics, part porosity and mechanical properties of the fused filament fabrication (FFF) process to provide insight into pore formation mechanisms and to establish guidelines for optimal process configurations.

Micro computed tomography and metallographic sections provide the basis for a correlation between porosity and extrusion path. Using the correlations found in this study, the way to improve printing strategies and filament properties can be deduced directly from an analysis of the print path and the final influence on mechanical performance.

With metal-FFF 3D printing technology, near-dense parts (0.5 Vol.%) can be fabricated. The pore architecture is strongly connected to the build direction and print strategy with parallel, elongated pore channels. Mechanical values of FFF samples are similar to metal injection-molded (MIM) parts, except the elongation to fracture. The high difference of yield strength of sintered samples compared to laser powder bed fusion (LPBF) samples can be attributed to the finer grains and a Hall–Petch hardening effect. The conclusions derived from this study are that the presented process is capable of producing comparable part qualities compared to MIM samples, with higher build rates in comparison to LPBF processes.

316L stainless steel was successfully manufactured via FFF. This paper also addresses the effects of scanning strategies on the resulting porosity and proposes improvements to reduce residual porosity, thus increasing the mechanical performance in the future.

Researchers began investigating the diffusion of renewable energy technologies (RETs) in the late 1990s, and, up to today, a variety of authors have presented different approaches to understand the special characteristics of RET diffusion. However, one factor has been thus far disregarded in the research: the influence of raw material prices on RET diffusion. The dependence of a multitude of technologies on raw material prices became especially apparent in recent years due to rather sudden and volatile price movements in raw material markets. Thus, the aim of this work is to contribute to the research by providing evidence for a direct linkage between raw material price developments and RET diffusion.

A theoretical framework used in this article derives from the concept of induced diffusion. This empirical study is based on publicly available data of 18 Organisation for Economic Co-operation and Development (OECD) countries over 20 years and uses multivariate regression analysis to identify the corresponding diffusion models for selected established and emerging RETs.

Results reveal that crude oil prices play a crucial role in the diffusion of emerging RETs. In addition, a joint reflection of induced diffusion and path dependencies as the theoretical foundation of RET diffusion models might be reasonable.

This paper makes a significant contribution to the literature on induced diffusion in the field of renewable energies by providing insights from publicly available data from 18 OECD-countries. The findings are highly relevant for managers of the energy industry and policymakers in this field.

This article is a collaboration between an academic researcher and four older people who worked together on the evaluation of a pilot project in Gloucestershire, with the aim of ‘making care homes part of our community’. Against a background of increasing public participation in research, we explore the role of ‘community researcher’ and the experiences of those involved. The article starts with an overview of policy and practice developments in relation to public engagement in research. A description is provided of a research project that included recruiting and training ‘community researchers’ to carry out an evaluation of the Partnerships for Older People Project in Gloucestershire. The next section focuses on the experiences of the older people who carried out this role, including some of the benefits and challenges that were encountered. The article concludes with a discussion of the implications for delivering meaningful public engagement in service development and evaluation.

Multinational companies are considered “driving forces” of globalization and “prime movers” of global sociation. Yet the problems, conflicts, and contradictions in the implementation of global strategies at the micro level – as well as the real possibility that such implementation will fail – are virtually ignored in macro‐sociological studies. Hence, the purpose of this paper is to address this neglect by focusing on a micro level examination of the contribution of expatriates in their interactive role as facilitators and managers, and, their informal social networks.

The interpretation of how global structures are concretely organized and sustained is based on case studies and interviews with German expatriates in Russia. The article examines two particular aspects: the contribution of expatriates in their interactive roles, on the one hand, and their informal social circles, on the other. The analytical framework draws on the concept of “global microstructures”.

Expatriates must maneuver between the conflicts and contradictions that surface from the three‐way relationship between head office, branch office, and the market, and their respective local institutionalized pressures. It is argued that such conflicts and contradictions cannot be resolved within the formal structure of organizations and that, as a result, they are shifted to the level of interpersonal interaction or to informal networks. Global reach as well as microsocial foundations therefore characterize the expatriate's action system.

Since the study is restricted to German expatriates in Russia, further comparative research is needed to sustain the findings for other institutional and cultural settings.

The findings raise awareness both of the contradictory demands expatriates are confronted with in their everyday work as well as their unique resources. They could contribute to better management training and preparation for expatriates prior to their move abroad.

The paper presents a micro‐sociological view on how systemic integration is actually achieved through a globally stretched as well as locally specified network of interaction. It could be valuable for international strategy definition as well as for personnel managers, and future expatriates themselves.

Knowledge competencies and (R&D) activities are one of the most important sources of innovation and have been widely discussed in the literature. In comparison, the role of the competitive environment for the innovation activities of firms is still open to debate and has not been fully understood yet. Therefore, this paper intends to provide new evidence on the interaction between knowledge competencies and R&D activities of firms on the one side and their competitiveness in the market environment on the other. In particular, the moderating function of market competition is explored. In this respect, the analysis covers the main innovation types as well as both sectors, manufacturing and services.

The empirical analysis is based on a three years panel dataset of German manufacturing and service firms obtained from Mannheim Innovation Panel (MIP) and Community Innovation Surveys (CISs: 2011, 2013 and 2015). For the estimation, a binary instrumental variable treatment model with Heckman selection method is used. Also, it provides a suitable approach to estimating the binary variables in order to cope with endogeneity concerns.

The estimation results show that R&D activities and knowledge competencies are positively related to innovation activities of different types conditioned on firms' specific perception of their competitive environment, in terms of outdated products/services as well as strong competition from abroad. Most importantly, the results from the moderation estimation reveal that there is a significant difference between the manufacturing and service sector. Service firms engage more in internal R&D activities on generating product innovations while the manufacturing firms conduct more external R&D on specific types of innovation. Further, the authors find that strong competition from abroad positively and significantly reinforces the effect of knowledge competencies on innovation activities for more types in services than in manufacturing. In contrast, outdated products and services tend to decline the effect of knowledge competencies for some innovation types in both sectors. The authors also observe a positive and significant reinforcement effect on knowledge competencies. However, it is found more beneficial for service firms since they can employ more innovation strategies.

The focus of the study is mainly on the impact of firms' competitive environment on innovation activities in various types through its interaction with knowledge competencies and R&D activities, across manufacturing and service firms.

The purpose of this study is to test and integrative model that forecasts a range of attributes as both antecedents and consequents of using a gamification app.

The proposed model includes factors from the technology acceptance model (TAM) [perceived ease of use (PEU), perceived usefulness (PU) and attitude towards use] and the self-determination theory (autonomy, competence and relatedness) as determinants of gamification usage. Additionally, the authors examine how job engagement (vigour, dedication and absorption) and organizational commitment (affective and calculative/continuance) are influenced by psychological outcomes.

PU, ease of use and a positive attitude significantly predicted actual gamification usage. Effective gamification usage predicted increased work engagement (vigour and dedication) and organizational commitment (affective and calculative). PEU predicted vigour when mediated by actual usage; and, dedication, affective and calculative commitment were predicted by all variables from the TAM when mediated by actual usage.

Companies should carefully evaluate the pros and cons of gamification implementation and its influencing factors for optimal organizational and employee outcomes.

By addressing both the psychological needs of employees and the technological factors influencing gamification acceptance, the study provides a more holistic view of the determinants of gamification success in the workplace, which is a fresh perspective in both gamification research and organizational behaviour studies.

The impact of building information modeling (BIM) on various aspects of project management has attracted much attention in the past decade. However, previous studies have focused on a particular facet of project management (e.g., safety, quality, facility management) and within identified target journals. Despite numerous existing studies, there is limited research on the mainstream research topics, gaps and future research directions on BIM in project management. This study aims to conduct a bibliometric and science mapping review of published articles on BIM in project management and to identify mainstream research topics, research gaps and future research directions in this domain.

A science mapping approach consisting of bibliometric search, scientometric analysis and qualitative discussion was used to analyze 521 journal articles that were retrieved from the Scopus database and related to BIM in project management. In the scientometric analysis, keyword co-occurrence analysis and document analysis were performed. This was followed by a qualitative discussion that seeks to propose a framework summarizing the interconnection between the mainstream research topics, research gaps and future research directions.

Six mainstream research topics were found including (1) BIM-enabled advanced digital technologies, (2) BIM-based reinforcement and enhancement, (3) BIM and project composition, (4) BIM project elements and attributes, (5) BIM-based collaboration and communication and (6) BIM-based information and data. Moreover, this study discussed six research gaps, namely, (1) integration of BIM and other digital technologies, (2) future maturity of BIM applications in project management, (3) application of BIM in project components and processes, (4) role of BIM application in project elements and attributes, (5) impact of collaboration and communication in BIM application and (6) stability of information and data interaction. Furthermore, future research directions were discussed.

The findings and proposed framework contribute to providing a deeper understanding to researchers, policymakers and practitioners in the development of related research and practice in the domain of BIM in project management, thus, promoting digital transformation in project management. Overall, it adds to the global knowledge domain in BIM and promotes the need for digital and data integration, BIM maturity and BIM collaboration.

Using the context of Rio Olympic games, the purpose of this paper is to investigate attitude toward sponsorship outcome as it relates to purchase behavior, gender, sponsor patronage, sports enthusiasm, and social media consumption.

Data were collected using an online survey of 265 participants. Questions regarding demographics, viewing habits, sports participation, enthusiasm, attitude toward Olympic events were included in the survey. The four sub-scales were sponsorship attitude, sponsor patronage, social media consumption, and sports enthusiasm.

The findings of the study showed that social media consumption is positively related to attitude toward event and sports patronage. There was a significant gender difference on attitude toward event, social media consumption, and sports enthusiasm. Predictors for making a purchase as a result of seeing a social media advertisement were gender, playing competitive sport, and social media consumption.

This study will add to the body of academic and practitioner research on sponsorship outcomes, and provides an opportunity for marketers to leverage social media networks for sponsorship communication.

As the use of social media networks has increased over the past few years, no previous study has investigated association of sports enthusiasm, gender, or social media consumption toward sponsor patronage which relates to consumers seeking out sponsors and being influenced to make a purchase as a result of marketing communication of sponsors.

This study aims to examine how corporate social responsibility (CSR) affected the attitudes and behaviors of employees in the European aviation industry amidst the COVID-19 pandemic and to explore any moderating effect of empathetic leadership.

Based on the social identity and social exchange theories, a research model was developed and tested against empirical data collected from employees of the European aviation industry, in 2021. Structural equation modeling and regression analyses were used for testing the hypothesized causal relationships.

Perceived CSR is directly related to work engagement and indirectly associated with work engagement and job insecurity via organizational pride. The presence of an empathetic leader does not intensify the effects of perceptions of CSR on organizational pride. Work engagement, in turn, impacts organizational citizenship behavior, while no such effect of job insecurity is supported.

This study provides insight into the underlying mechanisms via which CSR affects employees during a crisis. It, also, has significant implications on human resources management within the industries severely affected by the pandemic.

This paper aims to examine the influence of the work–family interface on both work engagement and the psychological capital (PsyCap) of the liquid workforce. Also, drawing from the literature on consumer behaviour, the second objective of this paper is to investigate the impact of work engagement and PsyCap on customer advocacy.

A dyadic study was conducted, comprising 200 nurses and 200 patients from different healthcare service providers of India. Structural equation modelling was used to analyse the responses collected from nurses and the patients whom they served.

The results confirm that the home–work interface has a positive impact on work engagement and PsyCap. The findings also confirm a positive impact of PsyCap on customer advocacy, but the effect of work engagement on customer advocacy was not significant.

This study confirms that to keep liquid workers engaged in their work and to enhance their personal PsyCap, an organisation should provide the opportunity to maintain a balance between work and home needs. The findings also confirm that personal psychological resources (PsyCap) facilitate prosocial helping behaviour, which keeps customers closer and maintains them as true representatives of the organisation.

The present study is one of only a few preliminary studies examining the predictors of work engagement of liquid workers. Also, an inter-disciplinary approach was taken to understand the link between employee-level variables (home–work interface, work engagement and PsyCap) and a customer-level variable (customer advocacy).
